TRIPLE ELEVATED SUPERFICIAL ESOPHAGEAL CANCER WITH MULTIPLE DYSPLASIA -A CASE REPORT-

Abstract

A 64-year-old man with epigastralgia visited to our hospital. Esophagoscopy revealed the presence of two lesions. One was a slightly elevated lesion located at the posterior wall of the middle third of thoracic esophagus 32cm from the incisor tooth with an irregular surface, and the other was a slightly elevated lesion located at the anterior wall with a flat surface. These lesions were stained yellow by iodine. The lesion of the posterior wall was treated three times by endoscopic mucosal resection (EMR). We did not perform EMR for the lesion of the anterior wall, because of the diagnosis of dysplasia. Again, a diagnosis of squamous cell carcinoma was made by biopsy specimens during endoscopic observation. We decided to perform surgery. Microscopic findings showed well differentiated squamous cell carcinoma. Two lesions of 28×18 mm and 12×10 mm in size were found in the middle thoracic esophagus, both of which had invaded only to the intraepitherial layer. Another lesion of 15×6 mm in size in the lower thoracic esophagus had invaded to the intra-proper mucosal layer. Multiple mild to moderate dysplasia 2-5 mm in size were recognized. In the reports, triple elevated superficial esophageal cancer is rare.
